A number that is the product of 3 and 23, two prime numbers. Fucking internet perverts.
Proffessor: The mathematical properties of the number 69, whilst limited, are uinfalingly fascinating.
Student: (raises hand) Yo, doc i got a question!
Proffessor: Yes good sir?
Student: Isn't 69 that freaky shit where she sucks your dick, and you eat her out at the same time?

a) A number that looks the same when rotated through an angle of 180 degrees.
b) The only number whose square and cube between them use all the digits 0 to 9: 69² = 4761 and 69³ = 328,509.
c) 69 = 1892 ÷ 473 + 65—the digits 1 to 9 appear on the right of the equation.
69 is the record number of children born to a Russian woman—she had 27 pregnancies all of which produced more than one baby: 16 pairs of twins (32), 7 sets of triplets (21), and 4 sets of quadruplets (16).
